Definitions

  • the invention relates to a process for the production of a prosthesis or partial prosthesis, as well as a prosthesis, according to the attached claims.
  • the disadvantage resides in that the gingival margin is not reproducible by 100% and in that two planes are on top of each other. A mathematically rigid line is required to be followed herein.
  • the denture base is typically milled out of a plastic material, wherein the tooth recesses are simultaneously milled.
  • the teeth can also be milled using any suitable material, such as a composite or ceramic material.
  • preformed teeth can also be used; in this case, the tooth recesses are adapted to the basal shape of the teeth.
  • EP 2 742 907 A1 provides improvement on integrating the teeth into the denture base, representing considerable advance over the previously known solutions.
  • the teeth can be realized either as single teeth, or as a dental arch, in which the adjacent teeth are connected to each other by constriction.
  • connection between the teeth and the denture base must, in any case, be testable and, in particular, permanently durable.
  • any suitable joint or composite compound, including an adhesive can be used.
  • the gap between the teeth and the denture base for the composite material can broadly be adapted to the composite material and other requirements by accordingly designing it by CAD.
  • the thickness is between 80 ⁇ m and 200 ⁇ m, usually about 100 ⁇ m.
  • the residual adhesive or composite compound which is swollen irregularly is then manually removed.
  • manual processing with a hand cutter is not only time-consuming, but also often produces inaccuracies between the designed and the actual prosthesis, associated with surface losses, especially in the region of the gingival margin. Due to the three-dimensional embodiment of the margin line, it is moved selectively or in parts if, for example, the dental technician removes too much material at one location, which is easily to occur during manual post-processing.
  • the object of the invention is to provide a process for producing a prosthesis or a partial prosthesis according to the attached claims and a prosthesis according to the attached claims, which is to be further improved with regard to the manufacture of the prosthesis, wherein significant progress has been made in particular with regard to efficiency in manufacture, but also with regard to the aesthetic result.
  • CAD is used to briefly add a 0.2 mm oversize of the outer shape of the teeth and/or denture base, for example in the region at least above and below the gingival margin, e.g. at a height of 10 mm.
  • the oversize is not provided at the points where the teeth and prosthesis base are joined or contact each other, but only outside of those regions.
  • the joint gap is maintained in the manner known from prior art, wherein the tooth recess is generously filled with composite compound, so that it is ensured that the joint gap is generously filled with joint compound or composite compound after insertion of the teeth, so that there are no more air gaps.
  • the teeth can be inserted into the tooth recesses by hand, or by means of a transfer template according to WO 2015/055790 A1.
  • the composite material is then cured using a known clamping device, for example, or any other device by which the desired contact pressure between the teeth and the denture base can be maintained to ensure safe curing of the composite compound.
  • the denture base which is now provided with teeth, back in the milling device.
  • the now hardened excess of composite compound which can as well be referred to as excess of adhesive, is removed by milling, as is the oversize of the teeth and/or the denture base, so that both the gum margin and the teeth as well as the denture base are in the original size.
  • a modified embodiment which reduces re-clamping inaccuracy to zero, it is to provide the dental arch, adhesive application and to provide the unit including the dental arch in the milling machine in the workpiece holder in the state of the denture base being clamped.
  • the 0.3 mm oversize for example, will be removed, so that the teeth, denture base and gingival margin or gum margin each have the original dimension.
  • the chain-line shaped gingival margin can be present exactly as designed with the help of the CAD program through mechanical removal of excessive adhesive, so that the aesthetic result of the prosthesis is considerably improved.
  • the oversize does not necessarily have to be provided for both the denture base and the teeth.
  • pre-formed teeth in standard sizes, i.e. without oversize, and, for example, to manufacture the denture base having an oversize of 0.15 mm. Nevertheless, cleaning and removal of adhesive residues can quickly and mechanically be performed in a suitable manner.
  • the region adjacent to the gingival margin is preferably free of oversize, i.e. in the original size.
  • this transitional area which can be, for example, 1 mm or 2 mm high, a large portion of the excessive adhesive accumulates, making it easier to remove.
  • the adhesive inaccuracy can be compensated for in the absence of a transfer template by implementing a tooth oversize, followed by milling to the original size.
  • the teeth or the dental arch can also be imprinted into the tooth recesses without a transfer template, and following hardening, the original dimensions of the teeth are still precisely realized on the basis of the second milling step.
  • the invention is not limited to the use of single teeth.
  • tooth segments or dental arches can also be used, wherein the tooth segments can be mono-bloc or multi-bloc.
  • a full prosthesis provided for 14 teeth can be fabricated in three portions with two trios and one arch of 8 teeth (3+3+8).
  • the invention is not limited to the type of division of the teeth, the tooth segments or the dental arch.
  • a defined region having a height of, for example, 10 mm is manufactured, with an oversize adjoining the gingival margin, i.e. above and below the gingival margin, and, during the second milling operation, is milled to the original dimension.
  • this solution only this region is subsequently traversed again with the milling machine and milled to original dimensions.
  • milling can be restricted, for example, to a band of 6 mm on the denture base and 4 mm on the tooth surface. This is extremely time-saving. However, a separate milling strategy is required to avoid damage of the tooth.
  • the oversize i.e. the additional layer thickness applied to the tooth and/or denture base, which differs from the original oversize, can, in a wide range, be adapted to the requirements.
  • a thickness in the submilimeter range is possible, especially between 0.05 and 0.8 mm, preferably about 0.3 mm.
  • the oversize can be a constant layer thickness, but it is also possible to realize the oversize as having an unequal layer thickness.
  • the oversize in the occlusal or incisal area can be selected more generously. This is due to the geometric effect of any “cant” of the tooth in the tooth recess if the tooth is embedded in the tooth recess without a transfer template.
  • An inclined position in the tooth recess then has the effect that the inclined position is lowest in the contact area between the prosthesis and the tooth, i.e. in the basal area, and greatest in the area of the tooth remote from the basal area. However, this is the incisal or occlusal area.
  • Oversize at the denture base is not directly correlated to the oversize on the teeth. If the only purpose of the setup without transfer template is to compensate for tooth position errors, the denture base can be fabricated in the original dimension, i.e. free of oversize, and the teeth can be fabricated having oversize. If only excessive adhesive is required to be removed, the oversize of the teeth can also be reduced to 0 or close to 0, in a modified embodiment.
  • the milling device is subsequently set such that the original dimension is again used in the second milling operation, wherein it is understood that care must accordingly be taken to ensure that a tooth that already exists in its original dimension will not be damaged. If pre-formed teeth are used, they typically are in the original size.
  • the oversize removal can then be reduced to the prosthesis base and the excess adhesive; in this respect, re-clamping errors or re-clamping inaccuracies can also be corrected retrospectively. In any case, it is important to remove excess of joint material.
  • any suitable material suitable for filling the gap between the tooth recess and the tooth in the basal area can be used as the joint material.
  • tooth adhesives known per se are used herein, which ooze out of the adhesive gap, where the excess is removed by milling after hardening.
  • transitional area The area free of oversize adjacent to the gingival margin is herein referred to as the transitional area. It can also be completely filled with excessive adhesive, so that the excess can suitably be removed by milling in one run.
  • the size of the oversize is a function of a retention accuracy of the prosthesis base in the milling machine, which has a deviation of less than +/ ⁇ 50%.
  • the oversized shape can be three times as large as a joint compound or composite compound between the prosthesis base and teeth.
  • FIGS. 1A and 1B are schematic views of the actual transfer of a tooth in the denture base in the original dimension into a tooth in the denture base having the original oversize, which is reduced back to the original dimension;
  • FIGS. 2A, 2B and 2C are detailed representations of realization of the oversize as shown in FIGS. 1A and 1B ;
  • FIGS. 3A and 3B are schematic representations of the distance of the oversize or the excess of joint compound for a method according to the invention in the embodiment according to FIGS. 1A, 1B, 2A, 2B and 2C .
  • a prosthesis consisting of teeth 10 schematically shown in FIG. 1 and the prosthesis base 12 schematically shown in FIG. 1 is fabricated using the procedure according to the invention.
  • the denture base has one tooth recess 14 each, with a gingival area 16 of tooth 10 each being accommodated in the tooth recess.
  • each tooth has an essentially flat, slightly concave basal surface 18 , and the tooth recess 14 is shaped accordingly.
  • the transition between tooth 10 and the denture base 12 is typically referred to as the gingival margin or gum margin 20 . It is present both on the vestibular side 22 and on the oral side 24 . As seen from a vestibular point of view, the gingival margin forms a chain line in a manner known per se, representing a prominent red/white transition in the patient's mouth, especially in the anterior region.
  • a gap 26 is provided at the transition between those two teeth. This gap is subsequently to be filled with joint compound or glue. When the soft adhesive is applied, it is squeezed out of gap 26 and flows into the area of the gingival margin 20 .
  • FIG. 1 first shows the virtual model of this tooth 10 with the denture base 12 in the relevant part.
  • the denture base is in the left part of FIG. 1 , as shown in the original size.
  • both tooth 10 has an oversize 30 and the denture base 12 has an oversize 32 .
  • This is generated virtually by CAD and represents a volume increase with constant layer thickness compared to the original dimension.
  • the transition area 36 between tooth 10 and the denture base 12 is free of oversize 30 or 32 . Therefore, the gingival margin 20 is free, but is covered by excess of adhesive, which is not to be seen in FIG. 1 , if the CAD virtual model is actually produced by milling.
  • FIG. 2 shows the right figure in FIG. 1 and then in the center a larger section thereof.
  • the same reference signs here as in the other figures are shown for the same parts.
  • Gap 26 is completely filled with adhesive. However, the adhesive laterally oozes out of the gap 26 , forming excess 40 of adhesive or joint compound thereon.
  • the excess of adhesive 40 completely fills out the transition area 36 , so that the oversize 32 more or less seamlessly follows the excess adhesive to oversize 30 .
  • FIG. 2 also shows possible dimensions for the upper transition area 36 and the thickness of the oversize thereon, wherein the upper transition area is about 0.6 mm high, as calculated from the gingival margin 20 , on both sides, i.e. 1.2 mm in total, and wherein the layer thickness of the oversize 30 , but also that of the oversize 32 , is about 0.3 mm.
  • oversize 30 and the oversize 32 i.e. the associated additional material that each was left after the first milling operation, is removed in a one-step operation.
  • a tool change can be made by using a milling cutter having a smaller diameter, specifically for the second milling step.
  • the prosthesis according to the invention is characterized by high precision without any misalignment of the teeth, even if no transfer template is used for installation, but the result is still aesthetically very successful.
